Senior Hydraulic Design Engineer – Water​/Wastewater Modeling

Senior Hydraulic Design Engineer (Water & Wastewater)

The Role: We are representing a premier international engineering consultancy currently expanding their core design team in Muscat. We are seeking a Senior Hydraulic Engineer to take full technical ownership of complex hydraulic modelling and detailed network design for a flagship regional project.

Note to Applicants: This is a pure, hands‑on, technical delivery role. You will be the project's technical subject matter expert. We are looking for an engineer who thrives on the precision of modelling and design rather than the administrative burden of project management. You will be expected to drive the technical design workload and ensure the highest standards of accuracy for the entire team.

• Technical Sovereignty: Lead the design, simulation, and optimisation of water, sewer, and stormwater systems through personal, hands‑on modeling.

• Modelling Excellence: Perform complex hydraulic modelling and detailed surge/transient analysis using WaterGEMS, SewerGEMS, and Bentley HAMMER.

• Technical Oversight: Review and validate design inputs and outputs, ensuring technical excellence and compliance with international codes.

• Design Leadership: Act as the technical authority, mentoring junior staff by demonstrating best practices through your own active design work.

• Documentation: Produce high-quality technical reports, detailed calculations, and IFC-level design outputs with minimal oversight.

• Experience: Minimum 12-15 years of professional experience in water and wastewater hydraulic design.

• Core Technical Focus: Demonstrated expertise in wastewater‑first projects; you must have significant experience in both gravity and pressurized (force main) systems.

• Software Mastery: Expert‑level, recent, and hands‑on proficiency in SewerGEMS and Bentley HAMMER is non‑negotiable. You must be able to demonstrate complex transient/surge analysis experience.

• Independence: Proven ability to work autonomously, delivering complex technical designs while simultaneously ensuring the technical accuracy of team outputs.

• Technical Depth: Extensive experience in transmission/distribution systems, pumping station design, and urban hydraulic infrastructure.

• Qualifications: Bachelor’s Degree in Civil Engineering (Master’s degree highly preferred).

• Total Package:
  1100
  -1,400 OMR per month (All-inclusive). Dependent Upon Experience
